34 weeks - big baby belly

"Your baby now weighs about 4 3/4 to 5 pounds and is about 19 inches long. His fat layers — which he'll need to regulate his body temperature once he's born — are filling him out, making him rounder. His skin is also smoother than ever. His central nervous system is maturing and his lungs are continuing to mature as well. You'll be happy to know that babies born between 34 and 37 weeks who have no other health problems generally do fine."
